Our Story
Bouwsteen Energy exists to create customer value by addressing key energy needs in East Africa
Bouwsteen Energy was created with one clear purpose: to accelerate East Africa’s transition to clean, reliable, and affordable energy.
Our journey began in Kenya more than a decade ago, when our engineers and project managers first started delivering solar installations across the region. Over the years, this team built a strong reputation for quality, innovation, and impact, completing projects for schools, hospitals, factories, farms, and commercial properties.
In 2025, we came together under a new name and brand: Bouwsteen Energy. Backed by our Dutch roots and driven by our East African base, we are evolving from an EPC company into a next-generation energy service provider. Our goal is to go beyond installations and offer businesses a holistic “Energy as a Service” approach, covering design, financing, management, and long-term sustainability.
We believe that access to clean energy is a cornerstone (“bouwsteen”) for growth and prosperity. That belief continues to guide us as we partner with clients and communities to build a resilient energy future for East Africa.
